Constitution Hall State Historic Site

James Henry Lane had a significant impact on Kansas history and is one of Constitution Hall’s more colorful characters. He was part of a large antislavery delegation that marched into Lecompton to protest the convening of the pro-slavery Lecompton Constitutional Convention in the fall of 1857. The nation’s eyes were fixed on this site, waiting to see what kind of constitution would be drafted and whether Kansas would join the Union as a free or slave state.
